Centre Hospitalier de l’Université de Montréal


Complete low voltage lighting system

With lighting bills going higher and higher, the building administration decided that while adding a new section to the building, they could try lowering the average cubic feet lighting cost.

The new section of CHUM (Centre Hospitalier de l’Université de Montréal) needed state-of-art lighting solution. The rest of the building needed to lower their lighting bill and give a better lighting to its visitors. With our expertise, we’ve been able to adapt a solution that would fit both the new section and the old section while keeping the costs at a minimum for a quick return on investment.
